Welcome to my page. This page has been designed to tell you all about index notation, squares and square roots and how they work. Hope fully it will prepare you for the upcoming maths test.
INDICIES EXAMPLE-
SUMMARY- You multiply the base by however many times the small number or index reads. So if the equation reads 45, you multiply the 4 five times like this: 4 x 4 x 4 x 4 x 4 If the question says to expand your answer would be the same as above, however if the question said to write in index form, the answer would be 45. If it said to evaluate you would write the answer to the sum. In this case, it would be 1024. REVISION QUESTIONS-Have a go at expanding and evaluating these: 1.1432. 963. 2524. 1055. 34 ANSWERS: 1. 14 x 14 x 14 = 27442. 9 x 9 x 9 x 9 x 9 x 9 = 5314413. 25 x 25 = 6254. 10 x 10 x 10 x 10 x 10 = 100,0005. 3 x 3 x 3 x 3 = 81 Now moving on to....... SQUARE NUMBERS SUMMARY- A number is squared or raised to the power of 2 when it is multiplied by itself.EXAMPLE-
SQUARE ROOTS
SUMMARY- The square root is a number when multiplied by itself gives the original number. EXAMPLE-
REVISION QUESTIONS- Have a go at these questions...
1. 5 squared 2. 3 to the power of 2 3. 42 4. The square root of 64 5.
ANSWERS
1. 5 x 5 =25 2. 3 x 3 =9 3. 4 x 4 =16 4. 64= 8x8- the square root of 64 is 8 5. 121= 11x11- the square root of 121 is 11 Now you know all about square numbers, square roots and index numbers, its time to get studying!!!P.S Hope you found this page useful =)Alice
